help with light switch

[mjk1009]

Hi

I'm trying to replace a single switch with a single dimmer switch, I've done a couple of these before no problem but this one is troubling me.

I have four live or comm wires which for the life of me I can't fit into the terminal securely just doesn't seem to be enough room.

Can I terminate 3 of the other wires separately without having to use the same terminal?

Picture of wiring attached

Thanks

If there is space in the galvy box ,put them in a connector strip and add a single conductor from it ,to the switch terminal.

Looks like there is space as you can see a Choc block in there already bottom right
